So your Battery seems to work.. but discharges a little too fast..
I would not run it with battery in this state.
Look for an equal hot spot on the pcb.
Since you have two devices (and your fingers can feal heat) you can even compare heat between them.
But honestly fixing might get complicated, if you cant spot something simple and obvious.
How did you fix gsm? reflow, reball, new chip, springs?

I was going to say...
that it could be your battery...but you made a brief mention you have a bunch of batteries...so I am assuming it shows the same symptoms regardless which battery you use,
and as well...it could have some little to do with your charge cable...
Buttttt....
all things considered ...if it is a n900 you messed with originally ...fixing the gsm...
well ...god ...anything ...right down to the bme may be wonky now.
How long after the repair you did...did the symptoms first start appearing?
Right away? or did it take some time to manifest?
If you can't quite fix it...saying the battery still wishes to get too much unbalanced incoming charge , thus making the chemicals in said battery a serious threat...
If you do get the bme even quasi stabilized ...
then you could perhaps safely use a dummy battery with a proper regulator and use it hooked permanently to usb, to supply it power.
a micro desktop maemo pc ...essentially...

well...
geez...
it is a long standing issue that predates your ownership even...
so it is a complete unknown as to what started the problem in the first place...
Kind of hard to go step by step through what got the device to this point ....considering you weren't even present when the past owner did whatever he did...
That just makes things that much harder to troubleshoot

The battery state is kind of saved on the n900, not on battery. (it is a flaw)
That gets confused if you switch batteries. So probably your old battery had 30% and got replaced with an empty one.
